Hi guys,
I'm working on IoT internal project.
I create a device in IoT service and try now to new create a "new thing" in app Thing modeler of IoT AE.
Unfortunatly when I try to configure the connectivity after having fill the "Provider" field, I cannot see the sensor I previously defined in my IoT service.
I checked in "Data Ingestion error Log" tile and got the following messages on screenshot:
screenshot-data-ingestion-log-error.png
"Failed at device mapping"
Thanks in advance for you help
Regards/

There are 3 types of connections between iot service and iot ae:
- meta-data is sent via Kafka from iot service on device model changes to iot ae
- data is sent via Kafka from iot service on new measurements coming in to iot ae and a mapping has been created between sensor and thing
- commands are sent via http rest calls from iot ae on command api being called to iot service and a mapping has been created
The data ingestion error log is only for data (e.g. temperature: 15.0°), not for meta-data (e.g. sensor types, sensors, capabilities). So the fact, that you do not see the sensor meta-data points at a problem with connection type 1 from the above list.
For the first 2 of the above to work you have to have opened a ticket on the component BC-NEO-IOT-SVC to request a connection between an iot service instance id and an iot ae tenant id (same as the sub-account id in cloud platform cloud foundry). I would check this first in your case.
For the 3rd one to work you have to put iot service credentials into iot ae with the following apis: https://help.sap.com/viewer/350cb3262cb8496b9f5e9e8b039b52db/latest/en-US/75efcd5109ea43acbe7bf7dccb628058.html?q=target%20value .
